My unpopular opinion is Özil should play on right wing. Özil can give very good pinpoint crosses from the side. And then he can cut in as an inverted wingerÖzil and ramsey cant play in the same team there i said it
Özil should never play as central midfield. He can't shoot, doesn't want to shoot, can't tackle, can't wrestle for ball.
Best option though is still to sell Özil.
